earlier on preventing civilian casualties. a u.n. report came out today that talked about this is the fifth year in a row where civilian casualties in afghanistan have risen and while isaf caused casualties are decreasing, civilian casualties are on the rise. how does that translate into how the campaign is working? do you want to see a few remarks? there is omore on the war. we would like to open it up unless vernon has something to say. >> i am good. >> we have any questions? -- and do you have any questions? i guess we should use the microphone. please, go ahead. >> in your book, it was mentioned that petraeus wanted to be chairman of the joint chiefs of staff, but he was told that no way he was going to become joint chairman. could you tell us why he could not be joint chief of staff chairman if he was this good? >> that is a great question. he was not considered for the position as we rode in the book. in part it was because the rumor has it or the sources which i have which are second hand, washington is only big enough for one superstar and david petraeus is not it.
